ELIL'I'DN F. WILLIAMS, 0F ST. LOUIS, MISSOURI, ASSIGNOR TO WILLIAMS PATENT CRUSHER MISSOURI."

& PULVERIZEB. COMIANY. OF ST. LOUIS, MISSOURI, CORPORATION OF To all whom t may concern.'

Be it lmown that I, MILTON F. WiLLIAMs, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in ReducingJ Machine Casings, of which the following is a full, clear, and exact description; suchas will enable others skilled in the art. to which use the same, reference being had tothe accompanying drawings, forming part of this specification, in whioh l Figure 1 is an elevational View showing the removable cover "in normal position. Fig. 2 is a detailed sectional elevation of a portion oI'l the cover removed.

This invention relates to Crushers and Shredders, and more particularly to a casingv for a Crusher or shredder wherein a portion of the easing is constructed in such.1nanner to be readily and easily removed to enable easy and quick access to the interior of the machine.

The principal object ofy this invention is to construct a casing for a pulverizer or shredder, which casing may he securely and i'ixedly held in normal position, and at the` same time so arranged as to be easilyy and quicklyI removed.

A further object of this invention is to construct` the removable section to apulverizer -orhredder casing which section is adapted'to carry conduit pipes and other parts in 1which `there is a slight liability of clogging, thus permitting such parts to be easily and quickly cleared.

A still further object of this invention is toprovide a removable casing for a-crusher or shredder which removable casing is provided witli a trough, or like member, adapted to receive and collect incompressible or metallicl nuts, small stones, etc., that are undesirable in iinisbed crushed or shredded product; for example, Where the pulverizer or shredder is being used to shred rags or st-raw for the purpose of making paper it becomes necessary that all iron nails, metallic nuts or articles of like character be removed.

A still further object` of this invention is to provide a cover in which a receptacle is arranged for receiving extraneous substances, Vsuch receptacle being so arranged asto be accessible from the exterior of the casing without endangering the hands or Specification of Letters Patent.

limbs of the. operatorv when removing the extraneous articles. A "'-'Y K Other and further' objects of this invenj-l tion will in part bej'obviousland Wll'gin part be pointed out in the specificatiohei'ewith following by references to v"the accompanying drawings.' Referring more particularly, to Fig. 1, a base frame 1 forms a support for a main frame 2. At the forward portion ofthe .main frame is arranged a hopper c'aryng a feed table which terminates over a'rotary breaker roll 5. The breaker roll 5 cornprises a cylindrical member 6 which' is' adapted to carry a seriesof breaker knives, or plates, 7. The cylindrical, member 6 is mounted upon journal 8 that carriesupon its outer end a pinion 9, adapted to coperate with a `worm screw A10, and the.;worm screw 10 is mounted upon arshaft 11^ which is provided with ahand wheel' 12. Shaft 11 passes through brackets 14 which are Carv ried by a swinging journal frame 1,5 that .is pivot-ally mounted upon the main frame 2 by means of trunnion bolts 16 or`any-oth'er desirable pivotal member. .The swinging journal frame 15 carries the `journals 8 of the cylindrical member and therefore the relative position of the swinging frame 15 .determines the relative position of the 'cy.

lindrical member. A horizontally arranged shaft 17 is mounted for rotation in journal brackets 18 that are mounted upon the main frame 2 and intermediate the j ournal blllckets 18 the horizontal shaft 17 carries a worm gear 19 which 'coperates with segmental f lgear 2O that is formed upon the lower edge of the svvingino frame 13. The horizontal shaft 17 at its hand wheel 21 and also carries a sprocket Wheel 22 which cooperates with' the chain 24 which leads to a similar sprocket and adjusting mechanism (not shown) at the other end of thejcylindrical roller, thus assuring alinement of the breaker roll 5 for all posi 100 tions of adjustment. The rotating shredder member 25 is mounted upon a shaft which is journaled in the main frame 2 and which carries a ly wheel E27'.l Series of shredder bars, or the grinding cage 28, is located in 105 main frame 2 beneath the rotatable shred- -dcr member 25 in such manner as tocoperate with the rotating shredder 25.

The upper front casing Q0 is fxcdly bolted to the lower main frame 2 and ca rI-ies near 110 L lfrontend is provided with a itsu per middle portion swinging eye bolts 30 t at `are mounted upon Cotter pins 31 ,which ass through braclrets'BQ on` a. rib `34 of t e front casing 29. The swinging 5 e e bolts 30 are adapted to swing through s ots cut in the rib 34 Aand in a rib 35 which is formedfintegral with a removable rear casing 36, tiius permitting the rear easing 36 to be xedly and yet removably clamped tothe front `casin 29, the removable. rear casing4 36 is provi ed with an upper cham *ber V37 in which is located ai transverse trough 38. The trough 38 is mounted withq -in the chamber 37, just above the inlet openit ing from the interior of the shredder, to the l `chamber 37. The front wall` of the chamber 37 is provided with a hand openingf39 which is normali closed by a cover. plate 40. The side wal sof the removable,l

rearVV casin are provided with si ht openl ings41w "chate likewise norma ly closed bylineansV of cover plates 42. During the `operation of: the shredder or pulverizer the y:rotating shredder member revolves at a 2.5 veryhighvelocity and therefore sets up an action more or less similartov that of a fan.

it is .desirable to prevent cloggingfof the grinder ca e surfaceand also of the upper chamber 3% side pipes or conduits 44are `provided connecting upper chamber 37 with the;central, interior, oreye portion, of the shredder. Both ends of-each connecting` -conduit member 44 terminate over openings 45.` and 46 in the side Wall of the removable casing 36 to which side conduits, or side pipes, `44 are attached. As the removable casing 36 is particularly arranged for easy access to Iits interior any tendency of the side ipes 44 to clog is very easily. and

quicky obviated; however, the more particular reason for the removability of the rear casing 36 is to afford an easy access to the interior of the shredder.

yA- vertical leverv rod 37 is pivotally wymount as at 48 to the main 'frame 2 and "is piv tally attachedtas at 49 to the removable casing 36.A A linlr rod 50 is con necd to the 'vertical lever rod 47, and also to a crank lever 51 ixedly mounted upon.

50- a rotating shaft 52, which sha-ft is journaled in brackets 54 that are mounted. upon slide ways 55 which extend from the main frame by means of brace rods 56. l The rotating. shaft 52is provided with an end lever 57.

klink rod 50, the .crank lever 51, 'together `with rotating shaft 52 and end lever 57,

forni a toggle linlc mechanism which enables the upper casing 36 to be,a quickly slid from normal posit-ion over the rotating shredder lto the open position indicated in dotted lines in Fig. '1. At the same time, however, y when the members are in normal position the casing is very lixedly secured to the main frame. I

Having thus described my invention all' that I claim is:

1. In a devicel of lthe class described in combination a rotary pulverizer member, a casingl for said pulverizer member, said casing being formed with a chamber in the upper part thereof,` conduit pipes leading fromsaid chamber; to the eye portion of said rotary pulverizer, and a receptacle in said chamber for extraneous matter.

2. In a device of the class described in combination, a rotary 'pulverizer member, a

casing for said pulverizer said casing being provided with a chamber having an'opemng exfldng into the interior of said casing, a trough memberarranged in vsaid chamber above said opening, conduit ,pipesleadin from said chamber in the 'proximity of sai trough to the eye portion of said ulverizer.

In a device of the class ascribed in,- combinati'on a. rotaryepulverizer member, a casing for said mem r, lsaid casing haviig"` a removable portion. formed with a chamber in the upper part thereof, conduit pipes leading from said chamber to the axial portion of said removable portion;- and a receptacle for extraneous matter in said chamber.

In testimony whereof I hereunto aix my signature in the presence of two witnesses, this 24th day of August, 1911.
